Handheld 3D skin printer comes out, or the best laser engraver?

The Physicist Organization Network reported on the 7th that researchers at the University of Toronto in Canada have developed a hand-held portable 3D skin printer that can print multiple layers of skin tissue to cover and heal deep wounds. This is the first device that can form, accumulate, and solidify skin tissue in place in two minutes or less, and is a new breakthrough in bioprinting technology.

Deep epidermis, dermis, and subcutaneous tissue can be severely damaged. The currently preferred method of treatment is layer thickness skin grafting, where healthy donor skin is grafted onto the epidermis and part of the dermis. Performing a layered thickness graft on a large wound requires all three layers of tissue from a healthy donor's skin so that there are few qualified skin donors. Defective skin donors can make the wound area not completely covered, resulting in poor healing.

Although scientists have developed a large number of tissue engineered skin substitutes, they have not been widely used clinically. At present, most 3D bioprinters are bulky, slow, expensive, and most importantly not suitable for clinical applications. The research team believes that the in-situ skin printer they invented is a platform technology that can overcome these obstacles while improving the skin healing process.

Reported that this handheld skin printer resembles a white tape dispenser, "bio-ink" consists of protein-based biomaterials, including the most abundant collagen in the dermis, protein fibers involved in wound healing, etc. They can follow each "tape" extends. The device is only a shoe box size and weighs less than one kilogram. It also simplifies the use of traditional bioprinters and greatly reduces the amount of operational training required. Now, the research team plans to add some functions to the 3d printer, including expanding the area that can cover the wound. Except for 3D printer, the laser engraver is another gadget that many companies love to use. They hope to conduct more human clinical trials in order to eventually revolutionize burn treatment.

Laser technology is widely been used nowadays, do you know any?

At the end of 2017, China's well-known laser radar start-up company, SAIHE Technology, announced the launch of its solid-state rader, the Pandar GT, which will provide partners with test samples in the first quarter of the year 2019. In April 2017, SAIHE had already launched the Pandar 40, a scanning 40-line laser radar.

According to CEO Li Yifan, Pandar GT started research and development in 2015 and applied a brand-new technology named ZOLO (Zoomable Light Oscillator) to achieve the dynamic adjustment, viewing angle, angular resolution and imaging center area. This laser radar is designed and developed for vehicle gauge and mass production. We then interviewed Li Yifan. He disclosed some undisclosed news to us.

Li Yifan said that the Pandar GT is in the research and development stage, so it has not yet passed the rules of the car. The plan is to pass all vehicle regulations in 2019. Also in 2019, they plan to achieve large-scale production of the Pandar GT, when the price of the Pandar GT is expected to be suppressed to hundreds of dollars.

As for the specific details of the ZOLO technology, it is not disclosed because it involves technical confidentiality. We are not aware of the Pandar GT's resolution for the time being. Judging from the provided sample images, we can judge that the local resolution will be higher than that of the Pandar 40. Li Yifan told us some parameters of the Pandar GT: The maximum vertical field of view of the Pandar GT is 30 degrees, the maximum horizontal field of view is 40 degrees, and the maximum detection distance is 200m. The 200m probing is also the standard that the Pandar GT mass production product will reach.

At present, the prosperity of automatic driving has set off a global R&D and investment boom in laser radars, especially solid-state laser radars, and many players have poured in. In addition to professional equipment such as solid-state laser radar, the laser cutter, laser engraver is a more everyday and easier-to-operate gadget, which is more suitable for more amateurish players.

Do you know what brand to choose when purchasing a robot vacuum cleaner? -part 2

The advancement of smart robots in Robot Vacuums allows people to use Robot Vacuums without spending too much effort or even spending time and energy at all.

If you want to do a good job of cleaning the floor in your home, you just have brains and memory that are not enough and you need to have excellent cleaning power. Traditional cleaning robots have appeared many obvious problems during cleaning. Because of the lack of power, many types of impurities cannot be cleaned. The TOMEFON TF-D60 Robot Vacuum has also made great efforts in cleaning.

The use of a roller brush enables the use of a floating roller brush for cleaning when there is a lot of dust and particles. It is worth mentioning that the brush bristles of the cleaning Robot Vacuum can also enter the gap during the cleaning process. This design makes it easier and more relaxing for people to get the floor cleaning done and without worrying about anything.

The TOMEFON TF-D60 Robot Vacuum also has a variable frequency suction nozzle, which can be switched freely and can target various impurities at home. People who have small pets in their homes may all spend time specializing in cleaning the fallen hair. When there is more hair on the ground, he will use relatively high power suction to clean the hair and keep the interior tidy.

When there is a satisfied cleaning robot at home, people usually do their own thing, so that they can make full use of their time. However, when a machine is in operation, it is inevitable that there will be noise, and the traditional Robot Vacuum will also have noise when it is working. The  TOMEFON TF-D60 Robot Vacuum can provide people with a more quiet environment after being innovative.

When people are resting and working, a Robot Vacuum has completed the sweeping of the entire home's ground. It does not require any specific operations by the people and does not affect people's sleep. It can be said to be quite ideal. What are you waiting for, why not choose a Robot Vacuum for yourself?

Do you know what brand to choose when purchasing a robot vacuum cleaner? -part 1

Some people say that people can make a better and higher quality service for people's lives by making a small progress in science and technology. Robot Vacuums are no stranger to people nowadays. They have entered people's daily lives, allowing people to see real cases where technology changes real life. People do not have to worry about daily household floor cleaning anymore, can take a real rest at home.

In most people's opinion, the choice of home appliances still depends on the brand. TOMEFON can be said to be the veteran-level brand of the Robot Vacuum brand. Because it takes a long time to enter this field, the accumulated experience is more than those kinds of brands who just recently starting to study how to make Robot Vacuums, and the innovation is more prominent. It is also said that this well-known German environmental company, in 2018, once again took the lead in the sales list of global sweeping robots. As the top-three brands of sweeping robots for eight consecutive years, the brand has also become a hot target for the media. What kind of charm does it allow consumers to maintain with such high enthusiasm?

The HSIR+ multi-matrix intelligent composition system is a new attempt made by the TOMEFON TF-D60 Robot Vacuum in terms of internal intelligence. Break through the memory technology of traditional Robot Vacuums, it can be done when the cleaning work is not repeated.

Because traditional Robot Vacuums can only clean a certain area during cleaning, they cannot master the overall cleanliness. With the technical progress of Robot Vacuums, this situation has also been significantly improved. Because there is an intelligent system inside, it is possible to scan and build the entire environment before the work is carried out, so that new types of Robot Vacuums can be used and became a Robot Vacuum with brain and memory.

How to purchase a suitable home Laser Engraving Machine? -part 4

Determinants of performance

The performance of a laser engraving machine is mainly determined by its engraving speed, engraving intensity, and spot size. Therefore, this can be the standard for us to purchase a home laser engraving machine.

Performance

Engraving speed refers to the speed at which the laser head moves, usually expressed in IPS (miles per second); high speed brings high productivity; speed can also be used to control the depth of cutting or engraving. For a specific laser intensity, the speed is higher. The depth of slow, cutting or engraving is greater. The engraving speed can be adjusted by the control panel of the laser engraving machine, or it can be adjusted by the computer's print driver. In the range of 1% to 100%, the adjustment range is 1%.

The greater the intensity of laser engraving, the deeper the depth of cutting or engraving. The spot size can be adjusted with lenses of different focal lengths; the small spot lens is suitable for high-resolution engraving; the large spot lens is suitable for lower resolution engraving, but it is the best choice for vector engraving; the usual standard configuration is a 2.0-inch lens with a spot size in the middle for a variety of applications.

Applied material

Laser Engraving Machine can usually engrave the following materials: bamboo and wood products, plexiglass, metal plate, glass, stone, crystal, Corian, paper, two-color plate, alumina, leather, plastic, epoxy resin, polyester resin, spray metal.

Application field

Used in electronic components, integrated circuits(IC), electrical appliances, mobile communications, hardware products, tool accessories, precision equipment, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipe, medical equipment and other industries.

Applicable software system

The laser engraving machine software system usually supports WINDOWS platform, and can be compatible with AUTOCAD, CORELDRAW, PHOTOSHOP and other software file formats, such as PLT, PCW, DXF, BMP, etc., and can also directly use SHX, TTF fonts. The graphics are designed freely through the computer, the operation is simple, the power is controlled by software, and the power is continuously adjustable.

How to purchase a suitable home Laser Engraving Machine? -part 3

Operating software

Using laser engraving and cutting, the process is very simple, like printing on paper with computer and printer; can use Win98/Win2000/WinXP environment to design with various graphics processing software, such as CorelDraw, scanned graphics, vectorized graphics and a variety of CAD files can be easily "printed" into the engraving machine. The only difference is that the printing applies toner to the paper, while laser engraving shoots the laser onto almost all materials such as wood, acrylic, plastic, metal, and stone.

Advantage characteristics

As a modern precision machining method, laser marking technology and Laser Engraving Machine have unparalleled advantages compared with traditional processing methods such as corrosion, EDM, mechanical scribing and printing:

1. The laser is used as a processing means, and there is no processing force between the workpiece and the workpiece, and has the advantages of no contact, no cutting force, and small heat influence, thereby ensuring the original precision of the workpiece. At the same time, it has a wide adaptability to materials, can make very fine marks on the surface of a variety of materials and has very good durability;

2. The spatial controllability and time control of the laser are very good, and the degree of freedom of the material, shape, size and processing environment of the processed object is very large, and it is especially suitable for automatic processing and special surface processing. And the processing method is flexible, which can meet the needs of laboratory-style single-item design, and can also meet the requirements of industrial mass production;

3. The laser scribing is fine, the lines can reach the order of millimeters to micrometers, and the marking and modification made by the laser marking technology are very difficult, which is extremely important for product anti-counterfeiting;

4. The combination of laser processing system and computer numerical control technology can form an efficient and automatic processing equipment, which can produce various texts, symbols and patterns, easy to design marking patterns with software, change the marked content, and adapt to the high efficiency and fast-paced requirements of modern production;

5. Laser processing has no pollution source and is a clean and pollution-free high environmental protection processing technology;

Fundamental

The basic principle of laser engraving is that a high-energy continuous laser beam is generated by a laser generator. When the laser acts on the substrate, the atom in the ground state transitions to a higher energy state; the atom in the higher energy state is unstable. It will quickly return to the ground state. When the atom returns to the ground state, it will release extra energy in the form of photons or quantum, and convert the light energy into heat energy, so that the surface material is instantly melted and even vaporized, thus forming a graphic mark.

Laser engraving refers to laser engraving, which marks the chemical and physical changes of the surface material caused by the light energy of the laser beam, or burns off some substances through the light energy, and displays the graphics and characters required for etching; it can be divided into dot-matrix engraving and vector cutting:

Dot matrix engraving

It is similar to high-definition dot matrix printing; the laser head oscillates left and right, each time engraving a line consisting of a series of points, and then the laser head simultaneously moves up and down to engrave a plurality of lines, and finally constitutes a full-page image or text; Dot matrix engraving can be used for scanned graphics, text, and vectorized graphics.

Vector cutting

Vector engraving is different from dot engraving, and vector cutting is performed on the outer contour of the graphic. This mode is usually used for penetration cutting on wood, paper, acrylic, etc., and can also be marked on the surface of a variety of materials. So if you are going to do some handicrafts at home, make sure your Laser Engraving Machine will offer you a nice vector cutting engraving function.

How to purchase a suitable home Laser Engraving Machine? -part 1

Basic overview

Laser engraving technology is one of the largest applications of laser processing. Laser engraving is a marking method that uses a high-energy-density laser to locally irradiate a workpiece to vaporize the surface material or cause a chemical reaction of color change, thereby leaving a permanent mark. Laser engraving can produce a variety of characters, symbols and patterns, and the size of the characters can range from millimeters to micrometers, which has special significance for the anti-counterfeiting of products.

The focused ultra-fine laser beam is like a tool, which can remove the surface material of the object point by point. Its advanced nature is that the marking process is non-contact processing, without mechanical extrusion or mechanical stress, so it will not damage the processed object; The size of the laser after focusing is small, the heat-affected area is small, and the processing is fine, so that a process that cannot be realized by a conventional method can be completed.

The “tool” used in laser machining is the spot after focusing. No additional equipment and materials need to be added. As long as the laser works normally, it can be processed continuously for a long time. Laser processing is fast and low cost. Laser processing is automatically controlled by a computer and requires no human intervention during production. So, no need to worry that the operation of the Laser Engraving Machine will be too professional for amateurs, it is quite user-friendly.

What kind of information can be marked by the laser is only related to the content designed in the computer. As long as the artwork marking system designed in the computer can recognize it, the marking machine can accurately restore the design information to the appropriate carrier. Therefore, the function of the software actually determines the function of the system to a large extent.

Breakpoints continue to work

In addition to the most critical path planning, the Xiaowa Robot Vacuum planning version also supports the breakpoint sweeping function. In large-sized sweeping areas, during half of the sweeping work, the power will be off and it will automatically return to the base for charging. After charging to 80%, it will return to the original position. Then it will begin to sweep again. The battery capacity is 2600mAh and can be cleaned for 1.5 hours on one charge.

Special Design

1800Pa wind power, obstacles avoiding, virtual walls and other functions are also on the same level of Mi Robot Vacuums, dust cartridge capacity of up to 640ml, only need to clean up once a week. At the same time, Xiaowa also uses the main brush, side brush, caster triple anti-hair design, home pet owner or female user consider it as very useful.

Mopping

In addition to the ordinary sweeping function, the biggest highlight of the Xiaowa Robot Vacuum planning version is that it has the function of mopping. The water tank is connected to the mop through the filter element and can support wet towing for 45 to 60 minutes. When it is not moving, it will automatically shut off the water.

High-cost performance

There are many functions such as App, and detailed information can be found on the official website. It has to be said that there are many great explorations of technology and algorithms in Stone and MI technology products. As for Xiaowa, Stone Technology may want to build it into an affordable brand and use more mature technologies to bring more cost-effective products to users. Now, the Xiaowa Robot Vacuum planning version is being pre-sold, the price is 1598 yuan, the final price after the pre-sale will be 1799 yuan.

The latest advanced robot vacuum from Xiaomi company -part 1

A few months ago, Xiaomi Ecological Chain Enterprise Stone Technology launched a "Xiaowa Robot Vacuum Youth Edition", priced at only 1,099 yuan. Because the Stone technology is the development team of the acclaimed Mijia Robot Vacuum, the brand "Xiaowa" is attracting attention. Unfortunately, the previous "Youth Edition" did not support map building and path planning functions. So today, Stone Technology has launched a "Xiaowa Robot Vacuum Planning Edition", and added the function of mopping and path planning to it. Pre-sale price is only 1598 yuan.

Intelligent path planning

Let's take a look at the path planning function of this Robot Vacuum planning version.

At the same time, with the 13 sensors installed, the Xiaowa Robot Vacuum planning version can integrate multiple data to form a sweeping map. When comparing the maps, the robot knows where to scan and has not been swept. In general, under the control of the double gyroscope, the Xiaowa can clean your home with a stable zigzag path, and the dual optical sensor can let it know where to go, and finally, with the sweep map, the Xiaowa Robot Vacuum can work like a MIJIA Robot Vacuum. Unlike other products, this Xiaowa Robot Vacuum planning version will not clean the floor such as headless flies.

Switch Vertical grip accessories Flip Grip Crowdfunding success - part 2

In June, the publisher Nacalis announced that its classic barrage-shooting game "Ikaruga" will officially land on the Nintendo Switch platform on May 29th for $14.99, and confirmed that the game will support portrait mode and will provide three difficulty options.

It was first published by Sega in 2001 and won praise from the media and players. Because the game needs to absorb black and white attacks, the difficulty of the original game makes many players miserable. More difficulty choices are also considered to be a benefit for players.

Currently the game has landed on Dreamcast, GameCube, PC and Xbox 360, and there have been reports of game landing PS4 before, PC players can purchase this game on Steam. However, if Switch wants to place the handheld on the table or hold it in the hand while playing on the vertical screen, it is somewhat troublesome for someone to open a crowdfunding project on Kickstarter. This is called Flip Grip's grip accessories. You can make your Switch more comfortable in portrait mode.

Switch Vertical grip accessories Flip Grip Crowdfunding success - Vertical play NS

At present, the project still has half a month to end crowdfunding, and the amount raised has reached more than $70,000, exceeding their target of $42,500. More than 4,000 people have chosen to raise this product. The price of the product is 12 dollars, which is not an expensive price. You guys should not miss the chance to buy such a good cost performance bluetooth game controller.

The Flip Grip has snaps that hold the Switch body and two handles. It also supports the desktop model to hold the main frame on the table. It is also designed with thermal issues in mind, so you will feel completely comfortable when holding it, and really enjoy your excellent game moments.

Nintendo Switch Vertical grip accessories Flip Grip Crowdfunding success - part 1

Recently, many flying shooting games have entered the NS platform. Users want to play NS on vertical screens. In order to solve this problem, crowdfunding site Kickstarter has launched a Flip Grip for NS, which is specially designed for vertical screens.

Fangamer FlipGrip

Flip Grip is actually a special handle controller that is made of sturdy plastic. The Nintendo Switch can be rotated 90 degrees counterclockwise, insert the Nintendo Switch until it is stuck, and then Joy-Cons will be on either side, and this is done.

Intimately, the inner edge of the Flip Grip handle is specially shaped as a Nintendo Switch and does not allow you to slide in the wrong direction. The inside of the Flip Grip also has a rubber bump that holds the Nintendo Switch firmly in place to prevent the console from falling during gameplay. To release the flip handle, press the release button on each Joy-Con and slide it up to remove it. Gently pull the small release tab on the back of the flip handle to unlock the Nintendo Switch on the handle.

And Flip Grip handles aren't just for handheld games, you can also think of it as a stand. At present, the price of this handle on the crowdfunding website is $12, and the price is not very high at all. Not only the Nintendo Switch controller but also the PlayStation controller can be very affordable too. I personally purchased a ps3 controller on a trustworthy online store and my ps3 gaming experience is really improved. Now, I no longer complain about my old game console, on the contrary, I quite enjoy playing some new popular games with that controller.

There are some games on the Nintendo Switch that support vertical screenplay, especially the flying barrage games, such as some of the games in The Donkey King, The Strikers 1945, the Ikaruga and The Gunbird.

Global wind power and solar power investment far exceed fossil fuels -part 2

In the future, photovoltaic and wind power will be used to generate electricity. Electric vehicles will be charged with sunlight and wind.

The technology of our battery has been developed. The characteristics of electric vehicle driving are basically the same as the use of a fuel vehicle as a vehicle, which has met one of the expectations. How much electrical energy is needed for an electric vehicle? From a professional point of view, we look at the problem in this way. The demand for electric power for electric vehicles does not depend on how many batteries are installed. The more batteries installed, the more electricity is charged, and the more driven distance. From the point of view of vehicle usage, fuel vehicles and new energy vehicles will not experience greater changes in driving mileage due to changes in power.

Soft pack batteries, one can ensure that the energy density can be high, other advantages, such as higher security, lighter weight, longer life, more conducive to our design and development, flexible loading, which is its advantages. If the consistency is not good, the overall system efficiency may be reduced, and reduce the overall system energy density. In the design and development process, how to solve the problem of poor consistency and poor storage? In fact, no need to worry that much, soft pack battery Charge Controller can be suitable for most needs.

Based on consistency from the preparation, storage of the battery core materials, there is no way for the embodiment of the entire process efficiency to be specifically invented and improved. Instead, each technology guarantees the achievement of consistency during the process. The final agreement is also based on a certain basis, to improve the consistency of the method to improve the consistency of the production to increase the error, the charge and discharge are uneven, how to effectively avoid the imbalance and design, to ensure a balanced performance.

Global wind power and solar power investment far exceed fossil fuels -part 1

According to the Wall Street Journal news on June 12, driven by the declining cost of wind power and solar power, global renewable energy investment continues to exceed coal power generation, natural gas power generation and nuclear power plant investment. The International Energy Agency (IEA) stated that in recent years, more than half of the world’s newly-added power generation capacity is renewable energy such as wind power and solar energy.

According to the IEA data, the global renewable energy investment was approximately US$297 billion in 2016 (the most recent documented year), which is more than double the US$143 billion investment in new nuclear power, coal, natural gas, and oil-fired power plants. The Paris-based agency expects that renewable energy will account for 56% of the net increase in generating capacity by 2025.

Thanks to cash back, tax deductions and other incentives, wind and solar power costs have been declining for 10 years, making renewable energy investments more competitive. Nowadays, products like Wind Turbine is not expensive at all, every family can depend on a Wind Turbine for basic life needs and save money.

Researchers say that the cost of renewable energy has fallen significantly in the past few years, and today wind power and solar energy have become the cheapest power generation options. Compared with traditional power plants, there are fewer challenges for renewable energy power plants.

GautamSne: India's Zero Emissions Target or Relies on Multiple New Energy Technology Paths

GautamSne said that in India, after the decision is made, there will be some new policies that will be specifically described. Of course, we understand this proposal. The government will establish a zero emission target. This goal is set by the government. How to do it does not necessarily mean that the battery will be purely electric. To achieve this goal, it may also be other paths and other forms. For example, hydrogen or fuel cells, or other technical options. Now there are some engine-related technologies. Of course, there are related improvements in efficiency, especially in the reduction of fuel consumption. The situation has improved.

Butterfleye Security Camera Shoots under Unusual Activities

According to the Ubergizmo website, Butterfleye is a simple, intelligent wireless home security camera that uses infrared technology to detect "abnormal" activities before it starts shooting, allowing users to "see and hear" everything happened at home even when they are not at home. The difference between Butterfleye and other similar products is that it only starts shooting when a pet, person or specific sound is detected. This eliminates the need for users to organize blank videos and also reduces the number of false alarms.

When an abnormal activity is detected, Butterfleye will use WiFi, Bluetooth, and cloud computing technologies to send notifications to the user's mobile phone. Over time, Butterfleye will be able to send notifications more and more intelligently because of its unique algorithm and multiple sensors that can understand the user's daily activities and habits. Some small events in the future, such as turning lights on or off, shaking the branches outside the house will not trigger Butterfleye to alert the user.

Ubergizmo said that Butterfleye's iOS and Android apps will provide users with a daily video of “abnormal” events during the day, allowing users to check for “abnormal” activities that occur on a daily basis. Butterfleye does not have a power cord. The configured lithium-ion battery can be used for 2 weeks after a single charge. This ip camera can capture full-HD video with a resolution of 1080p. The internal storage space can store 12 hours of video. It provides a free cloud storage service with a duration of 24 hours and can directly stream video over LAN/WAN/IP. Butterfleye integrates motion, sound, light and accelerometer sensors.

Butterfleye hopes to raise $100,000 through crowdfunding website Indiegogo and put it into mass production. The price of the first 300 units is 199 US dollars, and the price of Butterfleye after the limited quantity is 385 US dollars.

To protect student safety, New York officials proposed to increase surveillance cameras around the school

On June 19, 2018, the chief of the Municipal Police Headquarters, James O'Neill (spokesperson), appealed to the state government to install more surveillance cameras proposal as soon as possible.

According to reports of the United States "World News", the New York City Mayor's Office, the Municipal Police Chief James O'Neill, and Chen Wenye, director of the Municipal Police Traffic Safety Bureau, and others, publicly appealed to the state on June 18 local time in Brooklyn. The government passed a proposal to add hundreds of speed surveillance cameras around New York City’s schools to further protect students’ safety.

James O'Neill, Chen Wenye, Brooklyn Governor Eric Adams, Councilman Justine Brannan, and 264 Elementary School Principal Patrice Edison lead hundreds of students’ parents in 89 Avenue, 4th Avenue, the 264 elementary school entrance, appealing to the surveillance ip camera issue.

O'Neill said that at present, speed monitoring cameras are urgently needed around New York City schools. These cameras can effectively protect children from accidental traffic accidents during their studies. However, the state must first adopt proposals to promote the establishment of these surveillance cameras.

It is reported that there are now 140 speed surveillance cameras in the city, which were installed in 2014. After the installation, drivers who are speeding nearby have fallen by 60%, and the incidence of fatal accidents around the neighborhood has dropped by 25%. This means that the surveillance camera has a warning effect on driver's specification driving.

The current state government is reviewing proposals that will allow New York City to add hundreds of surveillance cameras to 150 different school districts. Although the proposal received bipartisan support, it has not yet been finalized.

For the proposal, Shirley Chin, the parent of a Chinese student on the scene, said that installing a camera around the school can curb the driver’s fast driving behavior and make the student’s safety more secure. I believe most parents will fully support it. However, some people also believe that the camera is just an excuse for the government to obtain more fines. At present, New York City is penalized for violations of speeding at 50$, and it can get government revenue of 100 million dollars each year.
